The present invention provides a concentration method of a fine particle dispersion containing fine particles to be electrophoretically migrated, for concentrating the fine particle dispersion by allowing the fine particle dispersion to flow in a laminar flow in a channel having a micro-width to which an electric field is applied in a direction intersecting the direction of a fine particle dispersion flow. The invention also provides a concentration apparatus of a fine particle dispersion using the concentration method.
